Triathlon one-piece suit

A triathlon one-piece, also called a tri suit, is worn for swimming, cycling and running. It combines the requirements of all three disciplines in one garment and saves you from changing clothes completely.

A well-fitting triathlon one-piece cannot slip during the race and lies against the body with as few creases as possible. Functional materials support moisture management and dry quickly after swimming. The exact properties depend on the respective model.

When choosing, the race distance, the expected temperatures, your personal focus and individual comfort requirements are decisive. Depending on the model, tri suits differ in sleeve length, zipper, material, cycling insert and pockets, among other things.

A tri suit should fit close to the body and with as few creases as possible, without restricting freedom of movement when swimming, cycling or running. At the same time, it must not dig in or cause chafing. The fit should therefore be tested in all three movement patterns.

Sleeveless tri suits offer plenty of freedom of movement in the shoulder area. Models with sleeves can offer advantages on the bike in terms of protection and, depending on the construction, aerodynamics. Which option suits you better depends on the distance, the intended use and your personal feel.

A front zip is located on the front and allows additional ventilation when cycling and running. A back zip is opened at the back and is often used on models that are more focused on swimming. The specific design varies from suit to suit.

A thin cycling insert improves comfort in the saddle without adding much bulk when swimming or running. Compared to the pad of classic cycling shorts, it is usually more compact and designed for a short drying time.

Yes, triathlon one-pieces can also be worn for long-distance races. Here, besides the fit, a comfortable cycling insert, good ventilation options and enough storage space for race nutrition are particularly important.

Over sprint and Olympic distances, low weight, a high degree of freedom of movement and a construction designed for fast swimming can be important. Additional storage space often plays a smaller role on short courses than over middle or long distances.

Pockets offer space for gels, bars or other small nutrition products. They are particularly practical over longer distances. Number, size and position vary depending on the model and should suit the planned race.

Some tri suits have special pockets in which ice can be carried for cooling. They can be helpful in races in hot conditions, but they are not available on every model or necessary for every use.

Individual models or certain material areas can offer certified UV protection. However, this does not automatically apply to every tri suit. Exposed skin should additionally be protected with suitable sun protection.

Yes, a triathlon one-piece is particularly suitable for brick workouts and race-specific sessions. This allows you to test the fit, cycling insert, ventilation and nutrition under realistic conditions before the race.
